UNA 25-PK and UNA 25-PS Ball Float Steam Traps with Pump Function

UNA 25-PK ball float steam traps with pump function primarily functions as a steam trap.

However, by integrating this steam trap with an automated pump function, you can discharge condensate, even under reduced steam pressure or high back pressure.

The condensate is then efficiently pumped out of the body using the aid of motive steam.

The UNA 25-PS has a pump function to return condensate with motive steam.

  • Reduce maintenance times
  • Save energy
  • Improve system reliability



  • Easy installation due to standard flange length
  • Corrosion resistant
  • Integrates with non-return valves
